Chapter 1. Manage data with Transact-SQL
Transact-SQL (T-SQL) is the main language used to manage and manipulate data in Microsoft SQL Server and Azure SQL Database. If you work with any of the Microsoft SQL products—as a developer, DBA, BI professional, data analyst, data scientist, or in any other capacity—you need to know your T-SQL. Exam 70-761 is a foundational exam that tests your T-SQL querying knowledge, and is a required part of several of the Microsoft SQL certification paths.
